Question

Read these instructions very carefully.

Name your source file midterm.cpp. Create a program that:

1. Opens a file called midtermInput.txt for reading.

2. Reads an integer and a string from each line in midtermInput.txt.

3. For each line in midtermInput.txt, reports, on standard output, if the length of the string is equal, more than, or less than the integer. Output should be in the form shown in the example run below.

Here are the contents of midtermInput.txt:

5 Howdy

12 Doody

6 Earth

7 Dinosaur

28 Antidisestablishmentarianism

Here is a sample run:

The length of "Howdy" is 5

12 is larger than the length of "Doody" which is 5

6 is larger than the length of "Earth" which is 5

7 is smaller than the length of "Dinosaur" which is 8

The length of "Antidisestablishmentarianism" is 28

To find the length of a string, use the size function, as discussed on page 356 of your text. Also, see the string class at cplusplus.com.
